The 51 members of the House are elected to two-year terms without term limits. The 25 members of the Senate are elected to four-year terms, also without term limits. Like many other state legislatures in the United States, the Hawaii State Legislature is a part-time body and legislators often have active careers outside of government.

Each session of the state legislature lasts for two years, starting in each odd year. Article III, Section 10 of the Hawaii Constitution states that the legislature must convene annually in regular session at 10:00 o'clock a.m. on the third Wednesday in January. Regular sessions are limited to a period of 60 working days, which exclude Saturdays, Sundays, holidays, and designated recess days.

The practical effect of having a two-year session is that any bill introduced in the first (odd-numbered) year which does not pass may be considered in the second year at the point in the process where its progress stopped. At the end of the biennium, however, all bills that did not pass the legislature die and to be considered must be reintroduced anew in the following session.

Article III, Section 7 of the Hawaii Constitution state that members of the Hawaii Senate must have been a resident of Hawaii for more than three years, have attained the age of majority and must, prior to filing nomination papers and thereafter continue to be, a qualified voter of the senate district from which the person seeks to be elected. An exception to this rule is that in the year of the first general election following district changes, but prior to the primary election, an incumbent senator may move to a new district without being disqualified from completing the remainder of the incumbent senator's term. Members of the Hawaii House of Representatives must also have been residents of Hawaii for more than three years, must have attained the age of majority, and live in their respective house districts.

In order to override vetoes by the Governor of Hawaii, both houses of the legislature must vote by a two-thirds majority to overrule the governor. Bills presented to the governor more than ten days before the end of that year's session must be signed into law or vetoed within ten days. Bills presented within the final ten days of the session have 45 calendar days to be signed or vetoed, provided the governor gives notice of what bills may be vetoed by the 35th day. The Legislature has the option of calling a special session on the forty-fifth day to vote to override any of the vetoed bills. All bills that are not vetoed or signed become law automatically without the governor's signature. (This system stands in contrast to the pocket veto power held by the president at the federal level.)

The governor also has extensive line-item veto power: bills that appropriate money can have their appropriations reduced or removed entirely by the governor before signing the bill (except where they appropriate money for the judicial or legislative branches). The state legislature does not have the power to override such a veto.[1]

The Hawaii State Legislature was moved to the Hawaii State Capitol in the Capital District near downtown Honolulu on March 15, 1969. The legislature moved temporarily to adjacent Capital District facilities when the Capitol was closed for four years in the 1990s for asbestos removal. The legislature moved back to the Capitol for the 1996 session. Prior to GovernorJohn A. Burns's decision to build the new Capitol building, the Hawaii State Legislature met at ʻIolani Palace.
